Name of the Vulnerable Software and Affected Versions
Valve's Game Networking Sockets versions prior to v1.2.0
Description
The issue arises from the improper handling of long unreliable segments in the function
SNP ReceiveUnreliableSegment() when configured to support plain-text messages. This leads to a Heap-Based Buffer Overflow, resulting in memory corruption and possibly even remote code execution.Recommendations
For versions prior to v1.2.0, update to version v1.2.0 or later to resolve the issue. As a temporary workaround, consider disabling the support for plain-text messages or restricting the use of the
SNP ReceiveUnreliableSegment() function until a patch is available.Exploitability
